In orderthat the detailed description which is to follow may be the more readily understood, l will til-st describe the general organization and operation of the machine.

l employ in the present machine, as in its predecessors, a series ot. matrices or Female type, each representing a single letter or character, and a series ot expansible spacebars.

Referring to Fig. l, A represents a rigid trame-work intended to sustain the various operative parts; ll, a series ol vertical maga zine-tulms containing the matrices or type; and (I, ejecting devices located at the lower ends of the magazines and operated by suitable connections from (niger-keys l), whereby they are caused to deliver the matrices one at a time from the lower ends ofthe magazine-tubes into the upper open side of an inclined conductoror trough IC. A pipe F, connectedv with a suitable blower, delivers a blast of air longitiulinally through the conductor E from its upper end, this blast serving to carrythe matrices forward to the point oli' assemblage or composition in the lower horizontal end ot' the conductor li. A receptacle Gr, containing the series ot space-bars, is located above the conductor E and provided with devices connected with a lingta'-key for delivering the space-bars one at a time downward into the line oli' matrices in the course ot' its composition. A pair ot vertically and laterally movable arms, one ot' which is shown at ll, serve to transfer the completed line to a vertically-movable yoke or railV l, by which the line islowered to the face ol.` a mold-wheel JV lying in fronti ol.' amelting-)mt K, from which molten metal is delivered into themold and against the line of matrices. 'lhe typebar or linotype thus produced in the mold is presented by the revolution of the wheel to an ejector-slide L, by which the bar is driven from the mold and carried Vforward to a lifting-plate M, which in turn delivers the bars successively to the lower end ot the galley N. After the matrices have formed the type on the bar cast against them they are carried by the lifting-yoke I to the top et' the machine and moved laterally therefrom by a slide t), between horizontal rails l), to a vertical slide Q, which, assisted by other devices, presents the matrices one ata time to the horizontal distribntingrail 'l`, along which they are moved by the endless carrier li until they drop into the upper ends ot' the appropriate tubes, the space-bars being in the meantime delivered downward bythe slide Q to their receptacle (-1.

It will be perceived that the object ot the mechanism is to assemble the matrices and space-bars and present them to the mold, deliver the molten metal against them, and, tinally, return them to the magazines from which they started.

ln its general organization and in all its leading features the present machine is substantially identical with that represented in latent No. STSJQS, to which ret'erence lnay be made for a detailed, description of such parts as are not specifically iflescribed herein.

l will now describe the construction of the present machine in detail, more especially with rel'erence to the features constituting the subjects of the present invention.

Referring to Fig. l, A represents the rigid main trame consisting' off a base plate o, having at its tour corners posts or pillars (1.', supporting a horizontal bed or table (L2, which in turn suplfiorts two nl nights a, carrying at IOO IIO

their upper ends the horizontal distributerframe a4.'

B represents the magazine composed of a series of vertical tubes b, arranged side by side and connected, as shown in Fig. 8, to a rigid frame h. top with two hooked arms b2, by which it is suspended from the stationary distributerframe a4, this connection allowing the entire magazine to be readily removed from the main frame independently of the key mechanism, to the end that it may be replaced by a magazine containing matrices adapted to produce a different style, or size of type. At its lower end the magazine-frame b bears against the rear side of the conductor E, and is held in place by a clipplate h3 and a fastening-bolt therethrough. This clip is notan essential feature and maybe replaced by any other suitable fastening.

The magazine-tubes l) are attached independently to the frame h', so that any tube requiring examination or repairs may be removed by lifting it out in a forward direction-that is to say, in an edgewise direction toward the operatorwithout disturbing the remainder. The mode of attachment to this end is plainly represented in Figs. 2 and 8, from which it will be seen that the bottom of the frame b is provided with a series of transverse grooves b4 to receive the lower end of the tube, and the tube provided at its top with a hook b5, adapted to engagea lip on the top of the frame ZJ. This construction holds the tubes in the exact position required, but admits of their being lifted from the front of the frame at will.

A bar h6, (see Figs. 2 and 8,) pivoted at its ends in the frame h', extends across the rear side of the magazine, and when free it drops downward and bears on plates attached to and forming in effect a part of thelower ends of the tubes in such manner as to prevent them from being lifted out of connection with the frame. Vhen the bar is turned upward, however, it releases the entire series of tubes, so that any one may be removed and replaced at will. It is to be noted that the tubes are not lifted endwise from their positions, but that, on the contrary, they are disengaged by a very slight vertical movement, after which they are removed horizontally. This independent removability of the tubes I consider an important feature of my invention.

Heretofore the magazine-tubes have been of an unbroken tubular form-that is to say,

without side openings or channels. l now construct them of the sectional form represented in Figs. 9 and 10, a sheet of metal, forming one side of the 'fiat tube, being bent inward or returned upon itself along its two edges in such manner as to produce a tube having one side closed, but the opposite side open centrally through its entire or substantially its entire length. This side opening bT is advantageous, in that it permits the escape of the air from the path of the descending This frame is provided at its.

, differentsizes.

matrices, and in that it affords ready access to the interior of the tube at all points in its length, so that a matrix lodging accidentally therein may be readily removed or adjusted. I prefer to construct the tube with the edges of the sheet projected inwardly in the form of ribs or flanges hs, and also provide the opposite or closed side of the tube with inwardlyprojected ribs b9. f By this construction the matrices are held out of contact with the inner faces of the tubes, thus reducing the friction, preventing the confinement of the air below them, and preventing them from ad` hering to the side walls in the event of the condensation of moisture thereon.

A further advantage arising from the construction of the tube with the open side lies in the fact that tubes of a uniform size externally may be readily adapted to receive matrices of different. thicknesses by turning the edges be inward to a greater or less extent, the cost of manufacture in quantity being much less than that of solid drawn tubes of The upper end of the tube is enlarged, and the iianges b9 and ribs b9 terminate below the enlarged end to facilitate the admission of the matrices.

At its lower end each matrix-tube is provided with an ejecting mechanism for delivering the matrices in a downward direction therefrom one at a time into the conductor below. This ejecting mechanism C (see Figs. 2, 9, and 11) is substantially identical with that represented in Letters Patent No. 392,446, dated November 6, 1888, and is not claimed in itselfvas a part of the present invention.

The ejector, which is secured to and is removable with its connecting-tube, consists, mainly, of an arm or plate c, fixed rigidly to and forming in effect a part of the tube, a lever c', pivoted to this plate, and a verticallymoving slide c2, operated by the lever. The

' slide carries a spring-finger c3, by which the matrices are thrust downward, and operates a pivoted detent c4, by which the escape of more than one matrix at a time is prevented. A sp1-inge5 serves to lift the slide and hold it normally in an elevated position. Vhenever the rear end of the lever c is raised, it depresses the slide and the matrix is delivered.

The finger-key mechanism D consists, as shown in Figs. l and 2, of a series of key-levers CZ, representing the respect-ive letters or characters, each mounted midway of its lengh on a horizontal pivot CZ', and arranged to act at its rear end on a vertical rod d2. The keypivots and the rods d2 are sustained by suitable supports on the bed-plate of the main frame, the upper ends of the rods bearing beneath the rear ends of lthe ej ector-levers c. The rods, being suitably guided and held in position at their upper ends, are certain to register with the levers, so that the magazine IOO IIO

may be removed and replaced with certainty The matrix conductor or channel .E is made, as in my priormaehines,oi' a U form in crosssection, with its open sides immediately under the magazine-tubes, in order that it may receive the matrices therefrom. The conductor is formed internally with the longitudinal ribs or shoulders c, upon which the shoulders at the upperends of the matrices rest, for the purpose oi retaining the matrices in an upright position as theyare carried length wise through the conductor by the force of the blast. To preventthe matrices from bein g overturned, I stretch longitudinally in the lower partot the channel two wires c',which engage shoulders on the lower ends ol the matrices, as in Patent No. 378,708. At their upper ends these wires are connected to a wiinling-spindle e2, Fig. 8, by which their proper tension may be 1naintaiued,and atthe lowerend are extended downward beyond the point at which they terminate in my previous machine and until they overlie the horizontal terminal portion of the guide E, on which the matrices are assembled. By thus extending the wires so that they hold the matrices down until their direction of movement is changed and they have commenced to travel horizontally I avoid the danger of the light matrices being overturned orbeing blown outot the machine. At its lower end the conductor E terminates, as in my previous applications, in the horizontal portion e, having the side walls to support, and sustain the line of matrices, but open on the under side that they may be rclieved from the lifting effect of the blast.

Instead oi delivering the entire blast drectly into the upper end of the matrix-channel of the conductor E and against the matrices delivered from the upper tubes, as in the previous machines, l now provide means for dividing the blast, allowing one portion to enter the upper end of the conductor and the remaining portion to enter the conductor at a lower point. By thus distributing` or dividing the blast and introducing the secondary or unweakeued blast midway of the length ot the conductor or thereabout I am enabled to carry all the matrices forward to the point of assemblage with rapidity and certainty, and this without employing a blast so strong as to cause the matrices to strike violently upon each other, or to cause the throwing of the light matrices from the machine. The pipes or passages for delivering the blast into the channel or passage of the conductor at different points in its length may be constructed in any appropriate manner. I have found it a good practice to make the channel at its upper end deeper than would otherwise be required and to introduce therein one or more horizontal partitions c, extending from the upper end downward half: the length of the conductor or thereabout. 'lhc blast-pipe F delivers the air partly above and partly below this partition. The upper portion ot' the blast passes over the partition el the entire length of the conductor, while the portion passing beneath the partition is inoperative, and is prevented from acting on the matrices until it emerges at the lower end ot the partition. While I have in practice found that it is suflieient to thus introduce the blast at two points it is manifest that it may be subdivided and introduced at any number ot' points in the length of the conductor.

At the lower end of the conductor I employ reciprocating dogs e, to advance the successive matrices against the liuc beyond them and to preventthem from rebounding. These dogs may be identical with those in Patent No. 378,708.

In order to arrest the descending matrices at the front end of the line, and thus keep the line in compact lform, I use, as in my previous machines, a transverse ii nger or resistant c, lying across the horizontal portion of the conductor, as in Fig. ll, and connected by a vertical pivot to a horizontally-sliding block c7. The linger is held normally in its operative position by a dog es, and its supporting-slide is urged. constantly toward the descenf'ling matrices by a spiral spring c, Fig. 4, these lfeatures being the same as in the earlier machines.

From the horizontal. end of the conductor the line of matrices is carried laterally into the lilitin or transferring yoke I, which stands normally in line with and forms a continua tion of the conductor, as shown in Figs. l, l, 1 8, 19, and 21. This elevating-yoke is moved vertically on a stationary guide z', so that it may descend with the matrices to the mold, and thereafter ascend with them to the distributer, its motion being eiectedv through a link 1l', connected to a vertically-vibrating arm i2, asin my older machines.

The transfer of the line ot' matrices to the lifting-yoke is effected, as in my earlier machines, by two arms H and ll', arrailged to swing downward into the conductor in such manner as to grasp the line of matrices between them, and then move laterally to carry the line into the lit'ti 11g-yoke. 'lhese arms are mounted, as in Patent No. 378,798, on a horizontal shaft 7L, carried by a block 7L sliding horizontally in a groove on the rear side of the conductor E. The devices for moving the slide 7L to and fro horizontally and for locking the slide in its normal position are practically identical with those shown in Iletters Patent No. 378,708, and form no part of the present invention. lith two exceptions the arms ll ll may be constructed and operated in the manner set forth in the abovenamed patent.

The iirst improvement consists in providin g the arm ll with a pivoted blade h2, (shown in Figs. Il, l5, and 16,) forming a downward continuation thereof, so constructed and arranged that as the arms swing douuiward to grasp the matrices Lhisblade will pass downward 1hrough the conductor E and past the rear end of the line. It serves, mainly, to bear against and hold the end of the line of matloq IIO

rices from shifting laterally out of position, so that they will be certain to pass the end of the clamping-jaw l7'2 as they are moved downward by the yoke to the casting mechanism.

The blade 71.2 may be modified in form and arrangement at will, provided only it is adapted to pass down vertically through the conductor. Then made of t-he particular form shown in the drawings, I mount on the frame a stationary pin h3, which, encountering the upper end of the blade, throws its lower end into the proper position to enter between the walls of the conductor. The second improvement, relating to the transferarms H and H', resides in providing' one of the arms with a rigid pin h4, extending laterally and adapted to pass at its end freely into a hole in the other arm. The arm H is mov- .able on its shaft to and from its companion,

being acted upon by a spring h5, as in my previous machine, so that the ltwo arms grasp the matrices with a yielding or spring pressure. As the two arms I-I H approach, the pin 7a4, sliding through the arm H, holds the arms together, so that they are compelled to rise and fall in unison. The pin avoids in a measure the strain and wear which would otherwise be thrown upon the sliding connection of the arm II to its shaft.

The lifting or transferring yoke I is grooved or ribbed internally along its sides to engage the shoulders of the matrices and prevent them from rising therein, as plainly shown in Figs. at and 21.

In order to insure the passage of the matrices smoothly and easily into the open end of the yoke, I provide the adjacent end of the conductor E with stationary side blocks eil-having inwardly-projecting lips el, beveled upward at one end. These beveled lips, overriding the ends of the matrices, hold them down snugly to their places, so that after leaving the conductor they are certain to pass properly into the yoke.

The mold-wheel J stands in a vertical position below and behind the lower end of the conductor E, and is provided with the slot or mold proper j through it from one face to the other, as in my prior machines. The yoke I, descending with the line of matrices, present-s and sustains them iu front of the mold-' Wheel and in such manner that for the time being they close the front of the mold proper, as plainly shown inFig. 22. W'hile in this position, the matrices are acted upon laterally-that is to say, from opposite ends of the line-and held tightly together by the two horizontally-movable clamps L7'2 and jg, as in of the line and guides the descending matrices properly to their places between the two jaws j? and jg. In this action it co-operates with the before-mentioned blade h2, which stands at the opposite end of the line, as plainly shown in Fig. 21. It will be perceived that during its descent the line is coniined at its ends between the blade h2 on the one side and the arm jg on the other. ception the construction and operation of the parts for lowering the matrices are substantially identical with that in Patent No. 37 8,7 98.

In order to give the desired results, it is necessary that the matrices shall be presented to the mold with their characters in exact alignment vertically. To this end one important feature of the, present invention consists in providing means by which the head or yoke I is locked down firmly and accurately in place during the casting operation. This construction, loy which the line of matrices is sustained in front of the mold, is plainly shown in Figs. 1S, 19, and 22, in which i3 is a horizontal rock-shaft mounted in the yoke and carrying atone end a hooked arm i4, adapted to interlock with a rigid portion of the frame and hold the head down to its place. At its opposite end the rock-shaft i is provided, as in Figs. 18 and 19, with a crank-arm 5, to which the link i for moving the yoke is connected. The crank-arm is 'allowed but a limited movement, and is held in an elevated position by a spring if, whereby its hook i4 is kept normally out of engagement with the frame. As the arm i2 descends, it carries the yoke and matrices downward until the yoke comes to a fixed bearing on the frame and mold-wheel, after which the arm i?, continuing its movement, causes the hook i4 to engage the frame and secure the yoke. Vhen the arm 2 rises, its first effect is to unlock, and its second to lift, the yoke. The essential feature of the improvement in this regard resides in the combination, with the rising-and-falling yoke, of an automatic device for positively locking the same down to its place upon the frame in front of the mold, and it is manifest that the details may be variously modified within the range of mechanical skill without changing, essentially, the mode ot' action.

As a further means of securing a proper alignment of the matrices, I now divide the yoke I for the first time horizontally, and connect its lower portion, which is grooved to receive the sustaining shoulders of the matrices to the upper portion by screws t? or equivalent connections, which will admit of the upper portion playing vertically in relationto the lower to a very limited extent. The devices for raising, lowering, and locking down the yoke are connected to the upper portion. Then the matrices are received into the yoke, the lower or movable portion, suspended loosely from the upper portion by the screws il, is in its lower position, as shown in Fig. 23. As the yoke descends, the lower portion, which alone sustains the weight of the Vith this eX- IOS IOS
